Abstract (en)
An electric power measuring system (100) capable of computing accurate electric power information using a low voltage measuring instrument in a small-scale electric power system is provided. The electric power measuring system includes a first measuring instrument (120) for measuring and detecting a current and a zero-cross point from a distribution line (110) and for generating and outputting current information of the distribution line (110) from the current and the zero-cross point, and a second measuring instrument (130) for computing electric power information of the distribution line (110) according to a voltage thereof and the current information output from the first measuring instrument (120).
